    <p>I have 4 Classes,</p> <ol> <li>FirstActivity</li> <li>Play_1</li> <li>Play_2</li> <li>Play_3</li> </ol> <p>onClicking a button in <code>FirstActivty</code>, I'll go randomly to the remaining three activities. For example, in the following code I came to <code>Play3.class</code>... I have set then handler to run for 3 seconds. My problem is during the <code>run()</code> time of 3 seconds, if I click the <code>backButton</code>, it will go to <code>FirstActivity.class</code> and after 3 seconds of <code>run()</code> time , it is going to the random loop again (<code>Play_1</code>, <code>Play_2</code>, <code>Play_3</code>). Now, I want to go permanently to the <code>FirstActivity.class</code> only when I click <code>backButton</code>. What Should I do?</p> <p>(NOTE: After completion of <code>run()</code> time of three seconds, I am happily going to home screen. But, During that <code>run()</code> Time only I want to Interrupt the loop and go back to the HOME screen.)</p> <pre><code>class listener implements OnClickListener { @Override public void onClick(final View v) { switch (v.getId()) { case R.id.play3_image1: bt1.setVisibility(View.GONE); bt2.setVisibility(View.GONE); bt3.setVisibility(View.GONE); bt4.setVisibility(View.GONE); bt5.setVisibility(View.GONE); bt6.setVisibility(View.VISIBLE); try { new Handler().postDelayed(new Runnable() { @Override public void run() { Random rand = new Random(); int x = rand.nextInt(3) + 1; Intent intent = new Intent(); switch (x) { case 1: intent.setClass(v.getContext(), Play_1.class); break; case 2: intent.setClass(v.getContext(), Play_2.class); break; case 3: intent.setClass(v.getContext(), Play_3.class); break; default: break; } startActivity(intent); } }, 3000); } catch (Exception e) { e.printStackTrace(); } } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(keyCode == KeyEvent.KEYCODE_BACK &amp;&amp; event.getRepeatCount() == 0 ){ Intent i = new Intent(Play_3.this,Example.class); i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(i); } return super.onKeyDown(keyCode, event); } } } </code></pre>

    1. COWhy don't you add boolean variable skipped = false; and populate it onBackPressed with true? Then just check if variable skipped == true before running handler.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
